Abstract
An inlet short pipe mechanism of a slurry pump belongs to the technical field of connecting mechanisms and comprises a connecting pipe, a first flange ring, a pipe base and a pressing cover. A left end of the connecting pipe extends into an inner cavity of a material box, the pipe base is formed by a first pipe and a second flange ring at the right end of the first pipe, a left end of the first pipe is welded onto a material box wall, and a left end of the connecting pipe penetrates through an inner cavity of the pipe base. A retaining ring is arranged on an inner cavity wall of the first pipe, a sealing ring is arranged between the connecting pipe and the first pipe, the pressing cover is arranged at the right end of the second flange ring, the left end of the pressing cover is inserted into a position between the pipe base and the connecting pipe, and the sealing ring is arranged between the retaining ring and the pressing cover. A welding position between the inlet short pipe mechanism of the slurry pump and the material box can not be abraded, maintaining work load is greatly reduced, and service life of the inlet short pipe mechanism is prolonged.
Description
Technical field
The utility model relates to bindiny mechanism, relates to a kind of slag stock pump import short tube mechanism specifically.
Background technique
The slag stock pump belongs to a kind of of centrifugal pump, and it is mainly used in industries such as mine, electric power, metallurgy, coal, environmental protection, and its centrifugal force that produces by the impeller rotation of pump carries slag to starch in the hopper that is communicated with the outlet of slag stock pump.As shown in Figure 1; Be existing slag stock pump import short tube mechanism structure schematic representation; It comprises connecting tube 1 ' and the flange circle 2 ' that is positioned at connecting tube 1 ' right-hand member; Used connecting tube 1 ' is an iron pipe, and the left end of connecting tube 1 ' communicates with hopper 3 ' welding and with the inner chamber of hopper 3 ', and flange circle 2 ' is connected with the outlet of slag stock pump through bolt.There is following shortcoming in existing this short tube mechanism: at first since the slag stock pump in running, the ore pulp of weld is very big through amount between connecting tube 1 ' and hopper 3 ', and flow rate of pulp stream is fast, so this welding part is easy to the leakage of wearing and tearing mill.
The model utility content
The purpose of the utility model provides a kind of slag stock pump import short tube mechanism, and the weld between itself and the hopper does not does not wear and tear, and has significantly reduced amount of maintenance, has improved working life.
In order to realize such scheme, the technical solution of the utility model is: a kind of slag stock pump import short tube mechanism comprises connecting tube and the first flange circle that is arranged at the connecting tube right-hand member; Wherein also comprise base and gland; The left end of said connecting tube stretches into the inner chamber of hopper, said base by first the pipe and be positioned at first the pipe right-hand member the second flange circle constitute, said first the pipe left end be welded on the wall of hopper; The left end of said connecting tube passes the inner chamber of base; The internal chamber wall of said first pipe is provided with a baffle ring, between the said connecting tube and first pipe seal ring is installed, and said gland is installed on the right-hand member of the second flange circle; The left end of said gland inserts between base and the connecting tube, and said seal ring is installed between baffle ring and the gland.
The utility model slag stock pump import short tube mechanism, wherein said connecting tube is a compound rubber pipe.
After adopting such scheme; The utility model slag stock pump import short tube mechanism through with the connecting tube of hopper joint outside set up base and gland; Replace merely directly with connecting tube and hopper welding manner, and connecting tube stretches into the hopper inner chamber, the ore pulp flow process is not is not worn and torn to the weld of hopper and base; Significantly reduce amount of maintenance, improved working life.
Description of drawings
Fig. 1 is the structural representation of existing slag stock pump import short tube mechanism;
Fig. 2 is the structural representation of the utility model slag stock pump import short tube mechanism.
Embodiment
As shown in Figure 2, the utility model slag stock pump import short tube mechanism comprises the first flange circle 2 of connecting tube 1, the processing of connecting tube 1 right-hand member, base 4 and gland 5.
Connecting tube 1 is a compound rubber pipe; The left end of connecting tube 1 stretches into the inner chamber of hopper 3, and base 4 is made up of first pipe 6 and the second flange circle, the 7 one processing that is positioned at first pipe, 6 right-hand members, and the left end of first pipe 6 is welded on the left wall of hopper 3; The left end of connecting tube 1 passes the inner chamber of base 4; Be processed with a baffle ring 8 on the internal chamber wall of first pipe 6, between the connecting tube 1 and first pipe 6 several O type O-ring seals 9 be installed, gland 5 is installed on the right-hand member of the second flange circle 7 through bolt; The left end of gland 5 inserts between base 4 and the connecting tube 1, and several O type O-ring seals 9 are installed between baffle ring 8 and the gland 5.
During use; The first flange circle 2 is spirally connected to be fixed together through the outlet of bolt and slag stock pump gets final product; Because the connecting tube 1 of the utility model short tube mechanism stretches into hopper 3 inner chambers, much ore pulps through amount are being got into the process of hopper 3 from connecting tube 1, ore pulp flows the weld of hopper 3 with base 4 is not is not worn and torn; Significantly reduce amount of maintenance, improved working life; Make connecting tube 1 into compound rubber pipe by existing iron pipe simultaneously; Solved steel pipe the problem that hinders dismounting slag stock pump has been set, when the slag stock pump is worked, shaken, caused the sympathetic response of hopper 3 but also solved existing iron pipe; Make the problem of iron pipe and the shortening in working life of hopper connection part; Connecting tube 1 is selected the rubber-like compound rubber pipe for use, when dismounting slag stock pump, pass through the slag stock pump flexible for convenience detach of connecting tube, and the rubber-like connecting tube can play good cushioning effect; Therefore the sympathetic response of connecting tube and hopper can not occur, just can not influence the working life of connecting tube and hopper connection part yet.
The above embodiment's appearance appearance is that the preferred implementation of the utility model is described; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in related domain make the technological scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
